You're right, Erica. I'm sorry. I was looking up a lot of different things at once and jumbled them together (very typical for me)...it's the S-H Spelling Bee that has the higher level course limits:
�The speller must not have completed nor ever been enrolled in more than six high school-level courses or two college-level courses on or before April 30, 2010.
Nothing to do with the math competitions.
